Overall Content Rating: Adults Only NC-17
This adult romantic suspense novel follows a newly assigned federal investigator who is drawn to a confident businessman while she hides who she works for and what she is investigating. Workplace ethics, secrets, and mob-related suspicion drive the tension; the relationship is a major thread alongside mystery and a series cliffhanger ending. Parents should treat this as mature-only content. Reader and author disclosures cite explicit open-door sexual scenes, adult themes, and frequent strong language. Physical intimacy is described graphically and often; profanity runs from mild exclamations to heavy use of the strongest terms, especially during emotional and sexual scenes. Violence is comparatively light but includes disturbing photo imagery and heated threats. There is no indication in the supplied notes of the listed themes such as LGBTQ+ identity, racism, abortion, or child harm.

Crude Moderate

About this book
Sparks ignited when I fell at Isaac Holt's feet—literally. Although his unique-colored eyes sheltered an arsenal of secrets, the immediate connection between the brooding businessman and me were undeniable. With lines crossed and a date penciled in, things were set to get roasting... until fate intervened. Even being my first week on the job won’t alter the facts—not even rookie federal agents are allowed to date their targets.
